History: The Polyester, Terylene[SUP]
®[/SUP], was developed by Imperial Chemical Industries in 1941. The rights were purchased by duPont in 1946 who subsequently developed the related similar fiber, Dacron[SUP]
®[/SUP]. The introduction of Dacron[SUP]
®[/SUP] rope in 1953 changed things again. The practical benefits of Nylon[SUP]
®[/SUP] were retained with the critical difference that elasticity was markedly reduced. In 1957 Samson introduced the Double Braid construction, and Dacron[SUP]
®[/SUP] ropes were rapidly adopted for halyards, sheets, and static climbing ropes.
- Properties: Dacron[SUP]®[/SUP] ropes stretched much less (about 3.5 - to 5% elongation at 30% of breaking strain) and were not weakened by water. Like Nylon[SUP]®[/SUP], Dacron[SUP]®[/SUP] has a relatively high density. It also melts before it carbonizes and the end of a rope can be fused using heat. It exhibits negligible creep under load and has excellent resistance to ultra violet light.
EDIT////////////
From the picture you've got it looks like it's a twisted rope rather than braided
